Fridge Flame issues

My Norcold 663 fridge works great on Electric and even on DC, when I switch to propane is where the issues start. I've had issues in the past with not cooling and a weak flame which is fixed by cleaning the burner but now my issue is the flame will go out after a few minutes or even seconds with a pretty good flame which sounds strong, it reignites runs for a short period of time (minutes or seconds) then it flames out and restarts and it will continue to do this.
I have replaced the ignition control and the spark with replacements from you guys (as something broke here with all the restarting) but it still has the same issue.
I'm running out of ideas apart from maybe issues in the propane line itself, but other propane appliances work well. Before I stored it for winter last year my propane tap seemed to leak when turning on and off, it was fine after taking it out of storage, that's why I am thinking it might be a propane issue.
Any ideas, anything else to check or replace?
Or is it time to find a professional?

That sounds like the flame sensor is either bad or has a corroded connection. It doesn't take much corrosion to interrupt voltage measured at less than 10 milliamps.
